Reliable, quiet, and easy to setup.By jlemoine2on 10/24/2012

I have two of these and use them for dosing 2-part calcium and alkalinity. Been using them about 18 months.

These are small enough to mount just about anywhere. I have them mounted in my tank stand and use an Apex controller to activate dosing at appropriate intervals. I use them on the mechanical switched outlets. I worry the digital outlets may not be able to detect the low power draw,

I gave 4 stars because the two units I have do not dose at the exact same rate... which leads me to believe they are not exactly 1.1 ml per minute. After the first couple of weeks of usage, I found I needed to run 1 pump about 3 minutes per day longer in order to dose my 2-part evenly. It's not such a big deal to me. I'm not sure if one of mine has something wrong with it, or if this is to be expected.... but I never bothered to call and complain about it.

Tried all other kind but love this pump. Slow speed and i don't have to guess how long to dose. Got 3 of these and they perform great and made in Italy too :). The only draw back is they kinda big but who cares? :D
Great products

THIS item is only for ONE PART of the 2-part dosing system-BEWAREBy Janettaon 9/16/2012

Janetta would recommend this product to a friend

I received it Friday and come to find out that it's only for one of the 2-parts although it's labeled as BSR 2 part doser. Buyers beware. I thought the add was very misleading and the item was expensive if you have to buy two of them.

Ever since I found out about BRS it's made life easier. Especially with these dosing pumps. Fast shipping, great price and very simple to set up. Stop wasting time and money looking elsewhere. Shop BRS.

I've had 2 of these up and dosing two-part for several weeks now. It seems like a very well built pump. I guess the reliability question will be answered in time. It dosed exactly 1.1 ml per minute for me. My pumps pull about 2 feet of head directly from gallon jugs, and deliver it over 15 ft away no problem.

I use the pump to feed a denitrator. The pump is connected to a collapsible bag - the type used in hospitals for intravenous drip and turns 3 times a day for 1 minute. I had so much trouble cycling y denitrator since I couldn't feed it consistently. The pump helped me cycle the filter in no time.

This is a very cheaply made doser, quite noisy and mine only lasted six months.

These dosing pumps enabled simple automation supplementing of pH and calcium using a controller. The purchase was well worth it.

Do Not PurchaseBy Jayon 4/17/2012

Jay wouldn't recommend this product to a friend

These are the least accurate pumps on the market, I have 3 and I'm sending the second one back. They start to drift after a bout 6 months. Do not trust. Do Not use. Please take this advice they are a complete waste of money and should never be used period. I have tests that show how poor these pumps are. It's really a shame that the best reef store on the market promote these horrible pumps. I lobe BRS and will continue to use them. But do not fall victim to these incredibly crappy pumps

Wow, this thing is bigger than my fist. It's working great though. A quick test revealed it is dosing at its advertised rate of 1.1mL/min. Quick to install and plumb, virtually silent operation, and it comes with tubing. Now I feel more comfortable leaving my tank in the hands of a housesitter.

Very easy to set up and get running. I have this controlled via an apex lite controller and set up time was minimal. Using included hardware I mounted it to my tank and got it plugged in and running in under a half hour. I bought two of them to dose two part and it definitely is nice to have my tank even more automated!

I bought 2 of these, one to dose Alk and one for Calcium. Very easy to hang, lightweight and includes both the hardline and soft tubing. I have this running on my Apex Neptune, so long gone the days of manually dosing!

They feel lighter than they look, and we usually associate quality with weight so only time will tell. So far i am very happy with them.
